Percentage positive is defined as the percentage of all domain items that the respondent coded as “agree” or “strongly agree.” Negatively worded items were reverse coded.

^aIndividual characteristics included in this model include occupational role, job tenure, and job hours per week.

^bFacility characteristics include whether nonprofit or government owned, whether chain owned, percentage of residents on Medicare, and total number of beds in facility.
